Script to Convert Maxsea Routes.
For old MaxSea 10 routes to import to OpenCPN, see attached perl script. The script may or may not work with other versions, or may require some tweaking. This will work only for routes pasted into a text file from the route center. To export there's a “Route Center” that brings up a spreadsheet-type view of all waypoints for a route. Make sure all columns are visible from the menu, then click in the top-left corner of the table to select all rows. There should now be a menu option to copy it to the clipboard, then finally paste it into a text file.
Then, rename the script to max2open.pl and then run:
$ ./max2open.pl <input >output.gpx
Or in windows, with perl in the path (I tried it with ActivePerl), something like this should work:
perl max2open.pl <input >output.gpx
A quick hack written to solve a specific problem, so it is unsupported, use at your own risk, and probably has serious bugs, etc
